Even though I voted to close (this question seems to me both off topic and subjective and argumentative), here is a kind of generic answer about the use of techonology in classrooms:

• if you have a clear idea about how you're gonna use it and if it has some useful feature that are not already available, then it is worth trying.
• but if the plan is to buy a very expensive gadget just because it's new, then I would recommend to avoid it.

My point is that one shouldn't be "Pro" or "Con": one should be very pragmatic and simply think about what one needs.
